I am having some problems understanding the difference in functionality provided by the HttpSessionAttributeListener interface and the HttpSessionBindingListener interface. Does anyone have an easy way of differentiating the roles of the above named interfaces? [ May 06, 2002: Message edited by: Ricardo Cortes ]

Actually, I think I finally figured it out. Correct me if I am wrong. If I have an object aBook of type Book, then HttpSessionAttributeListener will send out a notification when an object has been added, replaced or removed from the session whereas HttpSessionBindingListener will send out a notification (as long as Book implements the HttpSessionBindingListener interface) when aBook has been bound or unbound from the session. Is this a correct?
